Yes. In fact, zero-knowledge proofs make it possible for me to do something like prove my age in a way that is verifiable by the site without the site knowing any other information about me AND without the government knowing what website I’m asking. It doesn’t even require an API. The government needs to digitally sign my identity papers and publish its signature. One time download and you can even do offline checks.
The EU digital ID program does this. Everyone has privacy.
I think back to times I’ve eaten a thing and remember the sensation, then try replaying the feeling to see if it would be just as satisfying.
At the moment, I’m in the mood for a snack. I’m thinking about the dried fruit I had yesterday and the sensations it elicited when I ate it. Those same sensations of flavor and texture sound agreeable, so I’m thinking that would be nice.
Not everyone has this form of recall all the time. Some people have it intermittently. I asked my partner what she wanted to eat and she said she could not tell if she was hungry or if any food sounded good. I took this as a warning and we stopped at the nearest restaurant immediately. Fortunately, this was the right decision and we both felt better afterwards.
If you’re feeling hungry, imagine the smells of a food. Sense memory tends to run deep in people. If you find that you can’t recall or reject a sensation, that’s okay! Plenty of folks are in the same situation.
